From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dave Martin Subject: [PATCH 01/14] prctl.2: tfix clarify that prctl can apply to threads Date: Tue, 12 May 2020 17:36:46 +0100 Message-ID: <1589301419-24459-2-git-send-email-Dave.Martin@arm.com> References: <1589301419-24459-1-git-send-email-Dave.Martin@arm.com> Return-path: Received: from foss.arm.com ([217.140.110.172]:58158 "EHLO foss.arm.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1725851AbgELQhr (ORCPT ); Tue, 12 May 2020 12:37:47 -0400 In-Reply-To: <1589301419-24459-1-git-send-email-Dave.Martin@arm.com> Sender: linux-arch-owner@vger.kernel.org List-ID: To: mtk.manpages@gmail.com Cc: linux-man@vger.kernel.org, linux-arch@vger.kernel.org, linux-arm-kernel@lists.infradead.org The current synopsis for prctl(2) misleadingly claims that prctl operates on a process. Rather, some (in fact, most) prctls operate on a thread. The wording probably dates back to the old days when Linux didn't really have threads at all. Reword as appropriate.
